Under investigation there were 50 patients with resected stomach at different terms after operations: 37 patients after subtotal resection of the stomach for cancer and 13 patients after resection of 2/3 of the stomach for ulcer disease. The overwhelming majority of the patients with the resected stomach had chronic gastritis of the stump diagnosed endoscopically and histologically. No reliable difference of the endoscopic and histological indices of the state of the gastric stump mucosa was found in relation to the disease which was the cause of resection and to the time since the operation. The presence of Helicobacter pylori in the gastric stump mucosa was found in 37 of 50 examined patients (74%). In the group of patients with Helicobacter pylori in the gastric stump mucosa there were no reliable differences in endoscopic findings but changes in the histological picture were found significantly more often independent of the disease which caused the resection. Atrophic alterations in the gastric stump mucosa after resection in patients with Helicobacter pylori develop in patients of younger age and in earlier terms after operation.

Background: Gastric stump neoplasia is defined as a neoplasia that arises in the gastric remnant after at least 5 years of interval from the first gastric resection.
Aims: The aim of this study was to analyze 51 patients who underwent total and subtotal gastrectomy and multi-visceral resections in patients with gastric stump cancer.
Methods: The hospital records of 51 patients surgically treated for gastric stump cancer between 1989 and 2019 were reviewed.

Background: Laparoscopic distal pancreatectomy is a safe and effective surgical method for treating benign and malignant tumors of the pancreatic body and tail. However, laparoscopic surgery requires good intraoperative exposure, and since the pancreas is obstructed by the stomach and duodenum, making surgical operations and the management of intraoperative emergencies challenging. Therefore, gastric traction is crucial in laparoscopic distal pancreatectomy.

Background: Duodenal stump leakage is one of the most critical complications following gastrectomy surgery, with a high mortality rate. The present study aimed to establish a predictive model based on machine learning for forecasting the occurrence of duodenal stump leakage in patients who underwent laparoscopic gastrectomy for gastric cancer.
Materials And Methods: The present study included the data of 4,070 patients with gastric adenocarcinoma who received laparoscopic gastrectomy.

Background: Gastrectomy for gastric cancer with duodenal invasion poses an oncologic (high positive rate of resection line infiltration) and a surgical (high risk of duodenal fistula) challenge. This study aimed to validate the safety of gastrectomy for gastric cancer with duodenal invasion.
Methods: A total of 82 patients with distal gastric cancer who underwent gastrectomy and reconstruction via the Billroth II or Roux-en-Y procedure at Kobe University Hospital between 2011 and 2021 were retrospectively reviewed.

Gastric remnant volvulus following Roux-en-Y gastric bypass (RYGB) surgery is rare, with only two previously reported cases. Herein, we present the first case of gastric remnant volvulus following gastric sleeve conversion to RYGB in a 32-year-old female. Management for gastric remnant volvulus has not been clearly described in the literature due to the rarity of cases; however, previously documented cases of gastric remnant volvulus following RYGB were managed with gastropexy or resection of the gastric remnant.
